Convoy Battles of World War II occurred when convoys of warships protected cargo ships assembled for mutual defense and were attacked by submarines, surface ships and/or aircraft. Most were in the North Atlantic from 1939 to 1943 and involved attacks by U-boat wolfpacks. Convoy battles also occurred in the Arctic Ocean, Mediterranean Sea and western Pacific Ocean.
